OIL-CAKE TRIMMER.

Application filed March 12, 1915.

To all whom it may concern Be it known that I, JAMES WARNER RHODES, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented new and useful Improvements in Oil-Cake Trimmers, of which the following is a specification.

This invention relates to machines for trimming oil cakes.

In the manufacture of cotton seed and other oils, after pressing the oil from the meal in presses of ordinary type it is found that the extreme ends of the cakes still retain a considerable proportionate amount of oil, making it desirable to trim the ends from the cakes and subject the trimmings to further pressure.

The present invention has for its object to produce a simple and efficient trimming machine or device for this purpose.

A further object of the invention is to produce a cutting or trimming device which may be operated at high speed and which will be suliiciently strong to resist the use to which it is subjected.

- With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention.

In the drawings, Figure 1 is a side elevation showing the machine attached to a trimming table in position for operation. Fig. 2 is an end view of the same. Fig. 3 is a top plan view. Fig. i is a vertical sectional view taken on the line 4-4 in Fig. 3; Fig. 5 is a view in end elevation of the machine detached fromthe trimming table. Fig; 6 is a perspective view showing the spindle detached. Fig. 7 is a perspective view showing the trimming knives detached and separated from each other.

Corresponding parts in the several figures are denoted by like characters of reference.

The main frame of the machine consists of an angular or L-shaped casing or bracket B having vertical and horizontal arms 15, 16 and a reinforcing brace 17 The vertical arm 15 is apertured for the passage of bolts 18 whereby the bracket is securely mounted Specification of Letters Patent.

on the trimming table C, spacing sleeves 19 being employed for the purpose of properly spacing the machine from the table. A slot 20 extends partly through the arms 15, 16.

On the horizontal arm 16 are mounted bearing members or boxes 21 supporting a spindle S which is formed with a head 22 at one end thereof and with a pulley 23 intermediate its ends, said head and pulley being formed integral with the spindle. The latter is provided with a longitudinal axial bore 24:, and the head 22 is provided with intersecting diametrical grooves 25 affording seats for the knives or cutters 26. The latter are provided in their opposed faces with transverse recesses 27, whereby they may be secured together in interlocking re lation, causing the said cutters to lie in the same plane, portions thereof being seated in the grooves 25. The portions of the cutters that project beyond the circumference of the head are beveled to produce cutting edges 28. The cutters are also provided with central apertures for the passage of a bolt 29 which extends through the axial bore of the spindle and is provided with a. nut 30 whereby the parts are securely assembled. The boxes 21 are provided with lubricators or oil cups 31. An angular guard G is bolted on one of the boxes, said guard having a flange 82 overhanging the cutter head.

In constructing the device it has been my special aim to produce a trimming device which will be capable of being operated at high speed, say two thousand revolutions to the minute, and which will be extremely compact, solid and durable so as to be capable of resisting the strain to which it will be subjected, it being well known that the material operated upon is extremely tough and tenacious. As constructed by me the cutters are reinforced by the body of the.

cutter head, and the latter is formed integral with the spindle, avoiding joints or connections which would be liable to breakage or displacement. The driving pulley, likewise, is integral with the spindle, thereby preventing any possibility of its coming loose or slippm Having thus described the invention, what is claimed as new, is

1. In a cutting device of the class described, a spindle supported for rotation and having an integral pulley and an integrzil Gutter head, the latter provided with Patented July 4., 1916.

intersecting diametrical grooves, cutting members seated in the grooves of the cutter head, said members having interengaging recesses in their opposed faces, and means for securely mounting the cutters in the recesses of the cutter head.

2. In a cutting device of the class described a table a supporting member mounted on the table and spaced therefrom, a spindle mounted for rotation on the supportino' member and having a cutter head at the end facing the table, and cutting tools mounted on the cutter head and operating in the interspace between the table and the supporting member.

5. In a cutting device of the class described, a table, a supporting element mounted on the table and spaced laterally there from bearing boxes on said supporting member a spindle mounted for rotation in the boxes and having an integral pulley and an inte ral cutter head, the latter facing the table, cutting tools carried by the cutter head and operating in the interspace between the table and the supporting element, and a guard member secured on one of the bearing boxes and having a flange projecting in the direction of the table and overhanging the cutting members.

4:. In a machine of the class described the combination vvith suitable supporting means, of a spindle having an integral pulley, an integral cutter head provided with intersecting diametrical grooves and a lengitudinal axial bore, cutting members seated. in the grooves of the cutter head, said members having interengaging recesses in their opposed faces, and an assembling bolt extending longitudinally through the spindle and through the cutting members.

In testimony whereof I my signature in presence of two Witnesses.
